I was really interested in trying out Sylvania Silverstar headlights on my 2001 Pontiac Grand Prix, since the GP headlights are really really underpowered. As it turned out instead, one of the headlights in my 2000 Subaru Outback died first. So I replaced both sides with the Silverstars, just to keep them matched (so I had one good regular headlight bulb left over). I'm glad I kept the old light bulb, because 4 months later the driver's side Silverstar died. Then one month after that the passenger side Silverstar died too. So I've gone back to standard lightbulbs all around again, at 1/3rd the price (and probably 3 times the durability).
Now during the time I tried those Silverstars, I noticed their characteristics. The SSs do throw their light a little further out than regulars. However, I also noticed that the SSs don't have as wide an angle of dispersion as the regulars. I saw less stuff out the sides with the SSs than with regulars. I was more interested in getting a wider dispersion on the Pontiac than further distance, so the SSs would've been exact wrong type of lights to have anyway.
